Telomere length is not measured by physical length. It is measured by the actual number of repeats of the sequence.

- philsnow 10y agowell, isn't the telomere sequence just some sequence of base pairs, and all base pairs are the same length ? from https://en.wikipedia.org/wiki/Base_pair https://en.wikipedia.org/wiki/Base_pair : > one bp corresponds to approximately 3.4 Å (340 pm) of length along the strand so physical length and number of repeats of the sequence are the same, by some factor.
- daemonk 10y agoSure. But the question assumed that the physical length can be variable depending on the environment. Even if that was the case, measurement of telomeres by the sequence themselves will be independent of environmental factor. Maybe this is not the perfect analogy, but the character 'a' and the character 'A' might have different heights, but they still represent the same letter of the alphabet.
